The Dymaxion map of the Earth is a projection of a global map onto the surface of a polyhedron, which can then be unfolded to a net in many different ways and flattened to form a two-dimensional map which retains most of the relative proportional integrity of the globe map. It was created by Buckminster Fuller, and patented by him in 1946, the patent application showing a projection onto a cuboctahedron. The 1954 version published by Fuller under the title The AirOcean World Map used a slightly modified but mostly regular icosahedron as the base for the projection, and this is the version most commonly referred to today. The name Dymaxion was applied by Fuller to several of his inventions.

Unlike most other projections, the Dymaxion is intended purely for representations of the entire globe. Each face of the polyhedron is a gnomonic projection, so zooming in on one such face renders the Dymaxion equivalent to such a projection.
